[0027] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] Refer to Figures 1-5 , an anti-misoperation mechanism for a grinding device, including a grinding machine body 1, the grinding machine body 1 includes an installation cylinder 101 and a grinding wheel 102, an anti-misoperation structure 2 is provided on the grinding machine body 1, the anti-misoperation structure 2 includes auxiliary components 3, an anti-misoperation component 4 is provided on the auxiliary components 3, the auxiliary components 3 include a limit frame 301, an auxiliary assembly 302 is provided on the limit frame 301, the anti-misoperation component 4 includes a control assembly 401, and the control assembly 401 corresponds to the limit frame 301, and a protection assembly 402 is provided on the control assembly 401.

[0029] The limit frame 301 is located at the bottom of the installation cylinder 101 and is fixedly connected thereto. A partition board 3011 is fixedly connected inside the limit frame 301. The setting of the partition board 3011 can limit the moving block 4021. The top of the slide block 4013 does not exceed the bottom of the partition board 3011, and the bottom of the partition board 3011 is not lower than the top of the moving block 4021.

[0030] The auxiliary component 302 includes a U-shaped plate 3021 fixedly connected to the limit frame 301. A handle 3022 is fixedly connected to the bottom of the U-shaped plate 3021. The arrangement of the handle 3022 facilitates the staff to hold the grinding machine. A groove 3023 is provided on the handle 3022. The arrangement of the groove 3023 allows the fixing rod 4014 to be embedded into the handle 3022, making the two form an integral whole, which is convenient for holding the handle 3022 and the fixing rod 4014.

[0031] The control component 401 includes three sliders 4013 slidably connected to the limit frame 301. Cross plates 4011 are fixedly connected to the bottoms of the sliders 4013 on both sides. A row of teeth 4012 is fixedly connected to one side of the cross plate 4011. The row of teeth 4012 meshes with one of the gears 4023. A fixing rod 4014 is fixedly connected to the bottom of the slider 4013 among the three sliders 4013 that is close to the U-shaped plate 3021. One end of a first spring 4015 and a second spring 4016 are respectively fixedly connected to both ends of the slider 4013. Two of the three sliders 4013 are located on the side of the partition plate 3011 close to the U-shaped plate 3021, and the other slider 4013 is located on the opposite side. The fixing rod 4014 corresponds to the groove 3023. The other ends of the first spring 4015 and the second spring 4016 are respectively fixedly connected to the other slider 4013 and the limit frame 301. The driving force of the second spring 4016 on the slider 4013 is always greater than the driving force of the first spring 4015 on the middle slider 4013.

[0032] The protection component 402 includes a moving block 4021 slidably connected to the limit frame 301. The moving block 4021 is located between the partition plate 3011 and the slider 4013. A rotating rod 4022 is rotatably connected to the bottom of the moving block 4021. A gear 4023 is fixedly connected to the rotating rod 4022. The two gears 4023 mesh with each other. A protection plate 4024 is fixedly connected to the bottom of the rotating rod 4022, and the protection plate 4024 corresponds to the grinding wheel 102.

[0033] When in use, pull the fixing column 4014 towards the handle 3022. When the fixing column 4014 moves, it will drive the corresponding slider 4013 and cross plate 4011 to move backward, respectively pulling and squeezing the first spring 4015 and the second spring 4016. The first spring 4015 will then resist the middle slider 4013, causing it to press the moving block 4021 against the partition plate 3011. When the cross plate 4011 moves, it will drive the row of teeth 4012 to move, thereby driving the corresponding gear 4023 to rotate. Since the two gears 4023 mesh with each other, the rotation directions of the two gears 4023 are opposite. When the gear 4023 rotates, it will drive the rotating rod 4022 to rotate, and the rotating rod 4022 will drive the protection plate 4024 to rotate, thus opening the two protection plates 4024.

[0034] When the foremost slider 4013 moves past the partition plate 3011 and contacts the moving block 4021, as the fixed rod 4014 moves, the slider 4013 will drive the moving block 4021 to move together. When the moving block 4021 moves, it will drive the protective plate 4024 to move away from the grinding wheel 102 until the fixed rod 4014 is embedded in the groove 3023 of the grip 3022, and then grinding can be carried out.

[0035] When the fixed rod 4014 is released after grinding, under the elastic force of the second spring 4016, the corresponding slider 4013 will be pushed forward. The middle slider 4013 will push the moving block 4021 forward under the push of the first spring 4015 and the outer slider 4013, making the moving block 4021 and the slider 4013 relatively stationary until the moving block 4021 abuts against the partition plate 3011 again. At this time, under the push of the second spring 4016, the outer slider 4013 will continue to drive the cross plate 4011 to move, so that the row of teeth 4012 drives the gear 4023 to rotate in the reverse direction, so that the protective plate 4024 closes to play a role in preventing accidental contact.
